Subject: [GIT PULL] PCI changes for v4.7
Hi Linus,
Here are the PCI changes I intend for v4.7.
There is a silent conflict that needs to be resolved when you pull this:
- e3156048346c ("iommu/amd: Fix checking of pci dma aliases"), which is
already in your tree, added a use of PCI_DEV_FLAGS_DMA_ALIAS_DEVFN.
- 338c3149a221 ("PCI: Add support for multiple DMA aliases"), which is
included in this pull request, replaces PCI_DEV_FLAGS_DMA_ALIAS_DEVFN
with pdev->dma_alias_mask to support multiple aliases.
The conflict resolution I suggest is attached below. The identical patch
has been in linux-next and was supplied by both Jacek Lawrynowicz and Joerg
Roedel (and probably Stephen as well).
Bjorn

Subject: [PATCH] iommu/amd: Use pci_dma_add_alias function
The pci_dma_add_alias() function is the new interface and
replaces the old direct-access of 'struct pci_dev'. Convert the
last use of the old interface to the new one in the AMD
IOMMU driver.
